Re: [smartgrid-discuss] Pricing standards

I think we have to remember that we get the greatest interoperability from a *light* interface.

I may price my power because of a Utah mandated Tariff. To the California buyer, this is merely a price. If I am doing distributed generation from the Home Owner's Association of the recently built Off-TheGrid Neighborhood produced by [Comodity Homebuilder here], I may price my power based upon whether running the wind turbines does a better job of keeping Canadian Geese of the lawns….

The DR customer/recipient does not care how you came up with the price. In particular, I doubt that the decision maker receiving OpenADR price signals going to the Target Office in Minneapolis for stores in California cares at all which tariffs in California generated the prices. That decision maker is inward looking at his own business processes. What portion of the cost of my eggs at the store is due to feed or to shipping or to reduced margins during market surplus?

The supplier need to know how the supplier is pricing wares. The buyer needs to make bids and be held to them. And that's all. And pricing in this way is common for I2g/B3G/H2g/V2g…except where quantity discounts apply, which may be for I2g.

David,

I am new to this group. Just to provide some background, I am on IEC TC 57 WG 13, 13, 16, and 19.

Your doc mentioned TC 57 so I thought I would forward two things that I think are relevant:

1) A recent copy of the IEC 61970 Common Information Model. This is the data model described in UML that TC 57 uses for enterprise integration.   There is some modeling related to schedules in the CIM. This is an Enterprise Architect file.

2) A recent paper about ADR. This paper discuses the use of OPC Unified Architecture (OPC UA). OPC UA is the web services version of the services IEC 61970 specifies for exchanging CIM data. OPC UA is also known as IEC 62541. While OPC UA is new, it is likely to be widely supported by industrial control system vendors. As such it is a good choice for DR related communication with industrial customers.

You should know that EPRI and the IEC are beginning to actively work in this area. We probably want to figure out how things fit together at some point so that we don't end up doing the same thing twice.

Subject: [smartgrid-discuss] Pricing standards

All,

As part of the discussion on smart grid economics, in addition to schedules is the more general topic of pricing. I have written up some thoughts on what we need to do to move forward on pricing. Part of this is getting some standardized schedule as Toby mentioned. Perhaps a pricing standard will end up in OASIS as well. Does everyone know about the GridEcon meeting being planned for March in Chicago? The plan is to come with a pricing proposal in hand to that meeting, and I believe there is significant work to tackle prior to that time. Your input is appreciated.

David
